Reproduction steps:
1. Open the attached project “ReproProject“
2. Make sure the headset is connected (in case of Meta Quest, connect to the PC using wired Link or Air Link)
3. Find the render pipeline asset (Assets/Settings/PC_RP.asset), set “Anti Aliasing (MSAA)” to 2x, 4x, or 8x
4. Put on the headset and enter into Play Mode
5. Observe the result
Expected result: Foveation feature is working, the background will print out the shading rate, and you should see circular regions of 1x1, 2x2, and 4x4 shading rates
Actual result: The foveation is disabled, and the warning “Foveated Rendering disabled. Exceeded max sample count: 2 MSAA samples * 16 shading rate samples > 16 samples.” is being logged continuously in the Console Window
